Gemini (The Twins)
Gemini is the tropical zodiac Sun sign for the standard dates May 21 – June 20. A Mutable Air sign ruled by Mercury, Gemini is traditionally associated with curiosity, exchange, adaptability, and connecting ideas. Those associations are interpretive themes rather than a fixed personality profile. A full natal chart can show how the Sun works with the Moon, Rising sign, planets, houses, and aspects, while exact birth details clarify a boundary date.

What are the Gemini dates?
Gemini's standard tropical Sun-sign dates are May 21 – June 20. That range divides into May 21–31 and June 1–20. The exact solar changeover moment can vary by year, time, and location, so a boundary-date birth should be checked from exact birth details rather than treated as a third or hybrid “cusp” sign.

Gemini element, modality, and ruling planet
Gemini is a Mutable Air sign ruled by Mercury. Air symbolism emphasizes ideas and exchange, Mutable modality describes adaptation and transition, and Mercury is traditionally linked with language, learning, movement, and making connections. These associations are interpretive and do not claim that a planet or sign causes behavior.
Gemini personality & traits
Within tropical Astrology, Gemini is traditionally associated with curiosity, language, exchange, and adaptability. Mercury symbolism emphasizes learning and connection, while Mutable Air suggests movement between ideas and perspectives. These are interpretive themes rather than a claim that every Gemini thinks, speaks, or commits in the same way.
Gemini in love & compatibility
In relationship astrology, Gemini symbolism highlights conversation, playfulness, variety, and mental connection. Traditional Sun-sign comparisons often connect Gemini with Libra, Aquarius, Aries, or Leo, but compatibility is not fixed by signs. The needs, communication, circumstances, and complete charts of both people add the meaningful context.
Gemini at work & career
Career interpretations may associate Gemini with writing, media, teaching, sales, technology, or other work involving ideas and exchange. That symbolism does not prescribe a career or guarantee aptitude. Education, experience, interests, opportunities, and the rest of the natal chart matter beyond the Sun sign.
What Gemini means in a full birth chart
Gemini themes may describe how curiosity, communication, and adaptability are explored through the Sun-sign layer of a chart. A Sun sign is only one part of a natal chart: the Moon, Rising sign, planets, houses, and aspects add further context. Zodigram uses birth date, exact time, and birthplace to calculate the full chart for reflection rather than diagnosis or prediction.

How Zodigram approaches Gemini
This page uses the standard tropical Sun-sign range stored in Zodigram's shared zodiac data. The exact solar ingress near a boundary can vary by year, time, and birthplace, so the calculator uses the supplied birth details rather than inventing a hybrid cusp sign.
Personality, relationship, and career themes are original Zodigram interpretations for reflection. They are not deterministic facts, scientific claims, professional advice, diagnosis, or prediction; a complete natal chart provides more context than the Sun sign alone.
